i'm thinking about this too.
I've found 16gb version for £190 inc in a sale, with £290 for the cheapest 32gb model.
Think i'm going to go for a 16gb tbh. £100 is a lot of money really.
Also, be aware that they're approaching the end of a cycle (~5 days, although could be any time) so an update is iminent. They might release a 64gb and push the prices down a bit for the smaller models.
